| 摘 要： | 标准的QSIM算法,由于基于全局状态表示来描述、推理系统的行为,对于复杂系统推理求解时会产生不可控分枝问题.文章提出一种系统分解的仿真算法,将定性模型分解成称之为单元的子模型.对单元分别应用QSIM推理,对单元间的关系通过约束传播使得子模型推理一致.这种系统分解仿真算法可大大降低QSIM算法的不可控分枝,提高系统的仿真效率.

| Abstract: | Whenthe system is complex,and the standard QSIM algorithm is applied,intractable branchingproblems may occur, because the QSIM algorithm describes and handles system behaviorsbased on the global states. This paper proposes a system decomposing simulation algorithm.This algorithm divides the qualitative model into some sub-models called components,separately simulate the components with QSIM, and keeps the components consistent throughconstraint propagation. The algorithm may greatly decrease the intractable branches andimprove the simulation efficiency. |
